Answer:
200 dollars
Step-by-step explanation:
Let's say p equals the cost price of the article. Since the man made 25% profit, that means he got 100% of what he originally paid plus another 25% of what he originally paid. In other words, he sold the article for 125% of the original price. Converting that to a decimal we get:
250=p*1.25
Some simple division gets us a cost price of 200 dollars.
